Application led September 7', 19;!2. Serial No. 719,175.

has for its object to provide an improved wall construction for the sides or endsl of4 railway earswhieh can be made entirely of metal, which will he strong, light, structuially simple, and inexpensive, and `which,

tnrthermore,will be very compeet, se that the eer will have maximum inside dimensions in comparison with its out-side dimensions.

The inventionI consistsin certain vnovel arrangements and constructions for Vcarrying into etlect theebove stated objects, and further, in the several improvements in the construction ot railway cars shown inthe accompanying drawings andwhich will be hereinafter described and claimed.` The invention is illustrated, in s. preferred embodiment, in the accompanying dravvings wherein* Figure l is side'eleyetion `olf part of ve railway box ear constructed in accordance With my invention; Fig. 2, a detail View of one of the sheet metal Wall elements forming` a part of said car; Fig. 3, an end elevation of the csr; Fig. 4, a sectional plan taken on line l-e of Fig. 1; Figs. l5 a d 6, Vertical sections on lines 5-5 amd64-6, respectively, of Fig. l, looking inthe direction of the arrows; Fig. 7, e Vert-ical sectional View taken on line 7-7 of Fig. 3, looking-.in the direction of the arrows, and Fig. S., a sectional plan taken online 8-8 of Fig. fl.

Like characters of reference designate lilre parts in the several -figures of the drawings.

rThe improved arrangement and devicesl constituting my invention might be employed in the construction either of the side Walls or of the ends of a railway cer, or both sides and ends.

Referring" to the drawings, designates one ot the side plates of a ear which, in the particular construction shown, an angle har outwardly turned and supporting s Wooden nailing strip 26 to which the roof hoatds 27 may be secured. The side sillv 28 is also shown es en angle bar which is intnrned to support a naiihg strip 29 for the floor boards 30. 3i designates one of the `side and end` singular gussets 39 (Fig. 5).

yend plates of the csi', and 32 an end sill, the y latter supporting floor boards 3G.

a nailing strip 33 :tor the The' corner posts 34 are preferably angle `hars riveted to the side sills 28 and the end sills-32 and secured tothe plates by means of the gussets35.

To complete the side framing 'of the ear', posts 36 and diagonal braces 37, 38 are provided which` for the purpose of giving strength,and'rigiditgg are angular inl cross section. Ihsve shown the posts ss consisting of "l" section members and the diagonal braces as simple angle bars. The posts are riveted to the side sills 9S of the cai` and secured to the side plates 26 by means of the The lower ends of the braeesl, 38 ere riveted tothe side sill. 'The upper end of' brace 37'is secured tothe gusset ,plate 35 and the upper end of brace i the Agesl* plate 3,9.

AThe Wall ot" the car consists of a numberl ot sli-eet metal elements 42, which aievsuhn stantislly alike except that in the construe' -tion shown the sheetl it the end of thev car is narrower than the next adgacent sheet 43. Each sheet is formed with a diagonally extending smooth area ifi dividing the sheet into two triangular areas which are formed with the groups of horizontallyextending ribs 45, the ribs of one Agroup 'diminishing in length from -the top ,tothe bottom of the sheet and the other diminishing in length fromthe bottom toward the top.` The sheets are preferably secured to the inner faces of the posts and diagonal breces,lhe latterV lying between the two groups Yof ribs or corrugations, The advantage of this arrangement is that in the first place, it gives a very light, strong and Waterproof structure, and, in the second place, utilizes for the ribs or corri-xgations, what may heteimed the Waste spaces between the posts and diagonal braces. It is necessary, in order that the framing of the car may be suiticicntly strong and rigid, to make the posts and braces some considerable thickness.` lt is 'for this 'reason that/,they have the angular cross sections shown. This, of course, adds to the over all Width ot the ear Without increasing its inside Width. By Arising sheet metal tor forming the side ,wall of the cai' the thickness et" the Wall structure as a Whole is not appreciably greater than the thickness of the 'framing elements. Strength is Niven to this compa-ratively thin sheet mete by iorming it With aey 'the''iibs f space is into and occupy the L framing members.

'.f'" l diagonal la ,49 of'uniform length between and groups of ribsO of diminishing length -or, corrugations rdescribed yand no wasted inasmuch as the ribs project spaces between the Figs. 3, 7 and 8 illustrate similar arrangeents applied to the construction of the end the car. The frame consists, in addition the parts above described, of posts/4:6 and braces 47, both'of these element-s 'being shownas consisting of Z-bars. The

endl consists of a single sheet of metal '48 formed with-a series of' corrugations or ribs the posts 46 x'ein the top to.the bottomof the car, or vice versa as the case may be, between the diagonal bra-ces and the end posts 46 on the It'- will be readily sons. Likewise the side wall structure might be. made' up of a greater or less number of i vis-ed which would come within Sheets than that indicated by the drawings.

While I have described my invention as eiqbdied'in certain preferred constructions, I jrealize that modifications could be dethe principles of the invention. I, therefore, do not wish to be understood as limiting the invention to the particulars shown and described.'

I claim: l

1. In awall structure for railway cars, 'the combination with framing comprisinor osts and diagonal braces, of sheet metal .wall elements secured tosaid posts and braces and'formed with ribs which project into and occupy the spaces between said posts and braces.

2. In, a wall structure for railway cars, the combination with a framing comfprisin posts and diagonal braces, both o meta and angular in cross section, of sheet metal wall elements secured to said posts and braces and formed with ribs which project into and occupy the spaces between said posts and braces. y

3. In a wall structure for railway cars,

,divides said sheet into triangular ;,osarse the combination within, framing comprisin posts and diagonal braces, of sheet meta wall elements secured to said posts and braces and formed between each post and the adjacent brace with a series of horizontally extending ribs diminishing in length from the top toward the bottom of the car, or vice versa as the case may be, which ribs project into the spaces between said posts and braces. l

4. In a wallstructure for railway cars, the combination with a framing comprising posts and diagonal braces, of sheet metal wall elements secured to said posts and braces which extend from post to postz said sheet metal element being formed with a diagonally extending flat portion toaccommodate one of said diagonal braces whichl areas"7 the latter being formed with ribs.

5. In a wall structure for railway cars, the combination with a framing comprisin posts and diagonal braces,of sheet meta wall elements secured to said posts and braces which extend from post to ostJ said sheet metal element being forme modate one of said diagonal braces which divides said sheet into triangular areas, the latter formed with horizontall extending ribs which diminish in length rom the top to the bottom of the sheet on one ,side thereof, and from the bottom to the' top on the other side thereof. l

6. In a railway car, the combination o'f a framing comprising angle bar corner posts end post, side posts and diagonal braces, all of metal and angular in cross section, and sheet metal/'end and side wall elements secured to the inner sides of said end Vand side posts and diagonal braces with the adjacent edb'es of the side and end sheets securedy to :the inner surfacesy of said angle bar corner posts, said sheets formed with horizontally extendin ribs projecting into the space between said braces and posts.
